simple file I/O question

i have not done file IO in a long time so can someone awnser this question

will function fputc() work only when you are at the end of a file or will it replace what is in the file buffer with what you put in fputc() at the current place the file pointer is pointing to.

thanks

Google is your friend. man fgetc. . . or if you are on MinGW/*nix you could man fgetc.

Google's first post was this.

The latter. It will write the character at the current file position.
